The more detailed draw events should be available with r.RHISetGPUCaptureOptions 1. This will set a few cvars that emit a lot more data.
Alternatively, r.EmitMeshDrawEvents 1 will provide a breakdown. In 5.4, you will also need to set r.Nanite.ShowMeshDrawEvents 1 to get Nanite draw events.
Insights will need additional channels to see them too. I believe they reside in the RDG channel.
I hope that helps.
Best regards,
